A crown is a dental restoration that completely covers or “caps” a damaged tooth, while a bridge is a dental restoration that replaces one or more missing teeth.
A crown is typically used when a tooth is severely damaged or decayed, and a filling or other restoration is not enough to repair it. The crown is custom-made to fit over the remaining portion of the natural tooth, and is cemented into place to provide strength, protection, and improve the appearance of the tooth.
A bridge, on the other hand, is used to replace missing teeth by attaching an artificial tooth or teeth to neighbouring teeth or dental implants. The neighbouring teeth are prepared by placing crowns on them to serve as supports for the bridge. The artificial teeth are then attached to the crowns, creating a bridge across the gap where the missing teeth used to be.
Both crowns and bridges are made from a variety of materials, including porcelain, metal, or a combination of materials. Your dentist will help you choose the best material for your needs based on factors such as durability, aesthetics, and cost.
